Abstract
The invention belongs to the technical field of tobacco processing, and particularly relates to a process for paper-making method remade tobacco leaves airflow tobacco shred drying. The process for the paper-making method remade tobacco leaves airflow tobacco shred drying comprises the following steps: resurgence and airflow drying are conducted to remade tobacco leaves after being cut into shreds, and a moisture content of the tobacco shreds is controlled to 23-25%. The process for the paper-making method remade tobacco leaves airflow tobacco shred drying has the advantages of greatly reducing an attrition rate of the paper-making method tobacco leaves in a tobacco shred drying procedure, greatly improving effective utilization, increasing padding values of finished tobacco shreds, improving whole tobacco shred rate, reducing broken tobacco shred rate and tar yield of finished cigarettes, improving cigarette formula integrity, and enabling cigarette sensory quality to be close to a design value.
Description
Technical field
The invention belongs to technical field of tobacco processing, be specifically related to a kind of technique of drying silk for papermaking-method reconstituted tobaccos air-flow.
Background technology
Papermaking-method reconstituted tobaccos is made on the sheet base of being manufactured paper with pulp by offal, tobacco stalk fibre and wood-fibred with additive-coated the offal cabo extractive after concentrated, to be DDGS be filled in length by the effect of adhesive to its structure is in the fiber of about the 2mm network structure of forming, there is density little, Filling power is high, the advantage of releasing content of coke tar little (being only about 50% of tobacco leaf).Reconstituted tobacco is used widely in cigarette tobacco leaf formulation, and especially in Low-end Cigarettes formula, usage ratio is higher.
Current domestic Low-end Cigarettes processing is in drying process many employings pneumatic conveying drying mode, its high-moisture is utilized to get damp again and the feature of high temperature high velocity drying removes the bad breaths such as the blue foreign smell of low suborder raw material and xylon gas effectively, and can greatly improve cut tobacco Filling power, reduce cigarette weight, reach the object reduced costs with lowering harm and decreasing coking.
At present, a lot of Cigarette processing factory does not also possess the independent technology for making tobacco threds of papermaking-method reconstituted tobaccos and equipment, and papermaking-method reconstituted tobaccos still adopts same process, equipment hybrid process together with smoked sheet.But adopt the air-flow of smoked sheet to dry silk PROCESS FOR TREATMENT papermaking-method reconstituted tobaccos and there is following problem: high moisture regain moisture makes that the DDGS in papermaking-method reconstituted tobaccos inserts dissolves, the reduction of adhesive viscosity, the combination of inserts and fiber becomes not too tight, carry after high speed drying through high temperature gas flow, papermaking-method reconstituted tobaccos can produce serious solution fibre and make broken phenomenon, loss is serious, and effective rate of utilization reduces greatly.By finding Primary Processing master operation papermaking-method reconstituted tobaccos silk content detection, under state-of-the-art, export from chopping to pneumatic drier, papermaking-method reconstituted tobaccos loss reaches 40%.
For this present situation, prior art is improved from the process equipment aspect of the independent throwing of papermaking-method reconstituted tobaccos or packet transaction all emphatically, and be only limitted to adopt traditional drum-type drying at drying process, do not relate to the advanced technologies and the equipment that improve its service property (quality) when adopting pneumatic conveying drying.
Summary of the invention
The object of the present invention is to provide a kind of technique of drying silk for papermaking-method reconstituted tobaccos air-flow, reconstituted tobacco loss in the process can be reduced.
The technical solution used in the present invention is as follows:
Dry the technique of silk for papermaking-method reconstituted tobaccos air-flow, comprise that the reconstituted tobacco after by chopping carries out getting damp again, pneumatic conveying drying, controlling moisture content of cut tobaccos after moisture regain is 23%-25%.
Preferred tobacco cut width is 1.1mm-1.2mm, slightly wider than the blade tobacco cut width of routine.
Be 12% according to material moisture, carry out the mass flow that air-flow dries silk and control as 4500kg/h-4700kg/h.This flow for the specified production capacity of equipment (standard moisture 12%) be 4800 kg/h; According to the specified production capacity of equipment change to some extent, can adjust accordingly.
It is 180 DEG C-200 DEG C that pneumatic conveying drying operation process gas temperature controls.
Pneumatic conveying drying operation drying tube hot blast wind speed is 20m/s-25m/s.
The present invention is directed to structure and the processing characteristic of reconstituted tobacco, the technology condition that design is unique, thus reduce the loss in its process, improve effective rate of utilization, improve the integrality of formula, improve tobacco fill value, reduce tar content in cigarette.
It is broken that the conservative control of tobacco cut width can reduce making of chopping and course of conveying reconstituted tobacco; Control cut tobacco super moisture regain operation amount of water, by the water content conservative control after moisture regain, reduce the water absorption of reconstituted tobacco silk in warming and humidifying process, thus reduce dissociating after fibrous absorbent; The control of drying process mass flow considers that the unit interval is in the pipe tobacco amount in drying tube cross section, reduces the friction between pipe tobacco and between pipe tobacco and dry tube wall, and minimizing is made broken.The control of dry air-flow process temperature degree can weaken the dry tenacity of the instantaneous dry run of reconstituted tobacco; The control of pneumatic conveying drying operation drying tube hot blast wind speed, can reduce course of conveying material and mutually collide and collide with drying tube that making of causing is broken conciliates fibre.
After adopting technique of the present invention, after testing, papermaking-method reconstituted tobaccos significantly reduces in the proportion of goods damageds of drying process, and effective rate of utilization improves greatly; Finished cut tobacco Filling power raises, and whole cut rate improves, and filament broken rate reduces.Finished product cigarette tar content reduces, and cigarette composition integrality improves, and Sensory Quality of Cigarette is closer to design load.
